George Mitchell School in Farmer Road, Leyton, was visited by Ofsted inspectors in January after failings were found in October last year.

Pupil’s achievements, behaviour and safety, quality of teaching and the school’s leadership and management were all found to be not meeting basic requirements.

The all-through school was told to act immediately to finalise an improvement plan and clarify responsibilities, particularly in the primary school.

But in a report published yesterday, inspector Kekshan Salaria said issues had not been effectively addressed.

It was also found that plans were not “sharply focused” on rapidly bringing about improvement.

Headteacher Saeed Hussain, who had been in the post eight days at the time of inspection, was praised for quickly grasping the extent of the school’s weaknesses despite inheriting complex issues around staffing and accommodation.

Mr Hussain told the Guardian: “Whilst many positive comments were made about our students and the pride they take in the school, it is clear that we still need to focus our attention on moving the school from ‘requires improvement’ to ‘good’.

“Many improvements have already been implemented across the school and we believe we are on target to achieve our best results ever this summer.”
